HAIR-PIN.

Specification of Letters Patent.

Application lcd December 1B, 1909. Serial No. 533,786.

o all whom it may concern:

Be it known that I, Louis 'I'. HAnKNEss, a citizen of the United States of America, residing at Jamestown; in the county of Chautauqua and State of New York, have invented certain new and useful Im rovements in Hair-Pins, of which the ollowing is a specification, reference being had therein to the accompanying drawing.

This invention relates to hair pins, and the principal object of the same isto provide means therefor for holdin the pin in engagement with the hair, said means being arranged so thatj it will be invisible when in use and which may be readily re leased from its pin locking position to perreleasinf7 position.

mit the pin to be withdrawn from the hair. I In carrying out the objects of the invention' generally stated above it will be uhderstood, of course, that the essential features of the same are necessarily susceptible of changes in details and structural arrangements within the limits of the appended claims, one preferred and practical embodiment of which is shown in the accompany ingvdrawings, wherein z-- *igure 1 is a perspective view of the i m proved hair pin. Fig. 2 is a part elevation and part vertical sectional view thereof. Fig. 3 is a fragmentary vertical sectional view showing the locking device in a pin Fig. 4 is a perspective rovided view o an improved hair pin with means whereby a'chain cor or the like, may be connected thereto.

Referring to the accompanying drawings bynumerals, l and 2 designate the hollow tines of the improved hair pin which are connected at one end by the. inwardly curved hollow member 3 the outer upper rounded corner of each end of which is provided with an 'opening 4 that communicates with the 'tines'1-2. The free end of each tine is ointcd-to facilitate passage through the iiair. Intermediate their lon gitudinallength,

each tine is provided with an inwardlv' bowed portion 5, the inner surface of whic has an inclined opening 6 formed throurli it that communicates with the interior oi? the tines. A

, The locking device for the described pin is preferably formed of a :.,single length` of spring wire, y nector 8, and with inwardly curved free ends 9. Adjacent; .their junction with the conJ nector 8, each leg is provided with a bowed bent to form side legs 7, a con-.

or crimped portion 10, land intermediate their longitu inal length'each leg is 'provided with another'bowed or crimpedportion 11 said bowed or crimped portions 10,; l1 preferably projecting inwardly.

In Fig. 2 the locking device has been shown in its pin fastening position, the legs 7 of the saine having been forced through the' corner o enings 4 and through the hollow tines an having its inturned ends guided to and throu h the side openings 6 by the inner surface o the outer portion of the tines. When in' this position itwill be seen that the ends 9 of the locking device will have an interlocking engagement with the hair, and as said locking device has its upper crimp'ed or bowed portions 10 in interlocking engagement 'with theedge of the openings 4, the said device will belfirmly but detachably held in a pin locking position.

InvFig'. 3 the locking device lis shown in its pin releasing position, and by reference thereto 1t will be seen that the locking device has been moved longitudinally4 of the pin so that the ends 9 are drawn into the tines 1- -2 Patented oct. 4, 1910.

and the intermediate bowed or crimped portions 11 are in interlocking engagementwith the edges of openings that lthe locking device being formed of spring wire the same may be readily snapped rom engagement with the -edge of the openings 4 to slide the device to either its locking or releasing position. And it will also be 'obvious that the member 3 is inwardly bowed so that the' grasping of the member 8 by the fingers is facilitated.

In Fig. 4 the same type of pin and locking device is employed, but one of the tines carries a bearing 12 in which a ring 13 is pivotally mounted so that an eyeglass chain or the 4. It will be obvious like may be fastened to the ring.. Preferablyr 10, thereby assuring of a firmer engagement with the edge of the opening 4, so that danger of the locking device being pulled from the pin is prevented. l

That I ylaim as my invention'- is l.

1. A. hair pincomprising a pair of hollow tines having a connector at one end, said tines/each havin an opening at 4their lconnected 'ends and aving oppositelly imposed 10 single ength of resilient material shaped to inwardly facing openings intermediate their len th, and a lookin device having side legs sliible through 'sai o nings and tines and provided with end an intermediate means or engaging with the edge of the end openings for holding said device in either a locked or-unlocked position.

2. A hair pin comprising a pair of connected hollow tines having end and side openin and a locking device formed of a provide side legs having inturned ends adapted to be projected through the Vside openings of the tines and intermediate and end bowed portions adapted 'for engagement 15 with the edge of theend openings ofthe tines, saidlegs having an end v'connector that rojeets. beyondthe connected ends of the tlnes lto provldea. finger grip.

U In testimony whereof I hereunto aflix Iny 20 signature in presence of two witnesses.
